Hi all, I have a basic model as follow, but when I try to query the database, I get the following error: ''wrong number of arguments (0 for 2)'' I don''t see any problem, I am becoming crazy o_O'' Migration --------- class CreateSubtasks < ActiveRecord::Migration def self.up create_table :subtasks do |t| t.string :hostname, :type t.integer :task_id end end def self.down drop_table :subtasks end end Model ----- class Subtask < ActiveRecord::Base belongs_to :task end Code causing the error...

Hi all. I’ve heard a couple of times that some of the problems solved by various passes in the optimizer are indeed NP-hard, even though the instances are small enough to be tractable (and very quickly). Is this true? If so, which are these problems? Register allocation? Instruction scheduling? Are they solved exactly or by approximations? Or not solved at all (the need of solving them is

Hi: I''m trying to manually append objects to an instance variable that is just an array of objects. Here''s my controller code: @tasks = Task.find(:all, :conditions => "entity_id = #{session[:user].id}") for t in @tasks if Subtasks.find(:first, :conditions => "child_id = #{t.id}") != nil @mtasks << t end end However, when I execute, I get an error: You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occurred while evaluating nil.<<...

Dear R-lister Could anyone know how to make a multi-line title for a plot with expression()? In my plot, the title should be writeen in two lines (because it is two long for one line) and it should use a mathematical expression. I tried to use "\n", but "\n" is ignored in expression() call: hist(diffChangeRequestHintsBeforeAnswering[,4], br = 50, xlab = "Skill Change in

...================== The million dollar question is I have all of the team IDs and PPCS values for each call. How do I combine the entire set, build the table according to each column, and save the table data (from the rake task). Please keep in mind that TsosOffense.new is open and active for all subtasks.. I''m sure it''s something similar to TsosOffense.save (but I need to understand how to build the table with each data subset corresponding to the column). Thank you. -- Posted via http://www.ruby-forum.com/.

Hi My apology as I am really getting stuck. I know that this is not appropriate to post here but I do not know where to turn to. In any case, any thoughts or experience that you could share would be really appreciated. I have a need to use java to access R on windows. And I need to spawn each R process for each of my subtask in java application. That's why Rserve would not be the right tool

Hey all, I have a problem that I cannot wrap my head around. I have a capistrano task to kill my lighttpd process and restart it. Here is the subtask, stop_lighttpd, that fails: task :stop_lighttpd, :roles => :web do run "kill -9 `ps aux | grep lighttpd | grep #{deploy_to} | awk ''{print $2}''` > /dev/null" end I know for a fact that when stop_lighttp is

Student applications closed about 13 hours ago. Thanks to all the students who applied to us. We've made a start on reviewing proposals - please keep an eye open for emails or IRC (if you're on IRC) as we may have further questions for you. One general note - like many orgs in GSoC, we do expect students to contribute a patch as part of their application. This is very helpful as it

...y runs the functional and integration tests, but aborts with the same message when it attempts the unit tests. Among my changes were some shifting-around between a local SQLite database and a MySQL server, but I''d think that wouldn''t be a problem if the individual suites (and two subtasks of test) run normally. The problem persists no matter which DB I put in database.yml. I think the database issue is a red herring. "rake RAILS_ENV=test db:migrate" was run, with the expected progress output, before the rake test invocations. Re-running the migration outputs the "(in....

...back-when). >> do people use a password manager > Not for passwords, I remember all the ones I use a lot. Then I have a thought experiment for you: Let's assume that you found your workplace machine to be hacked and are now busy setting up a new one from scratch. Which of these two subtasks sounds easier to do: a) Create new keypairs, possibly reusing the old passphrases for them (because either you succeeded in making the new setup more secure, then reusing the passphrases won't matter, or you didn't, then the attacker would likely eavesdrop new ones soon-ish, anyway) b)...

I''ve spent hours researching the subject and have tried many test sequences in IRB, and rails console but I''m just having trouble making headway into what is probably a very easy subject. I understand arrays with at least 4 other languages but with Ruby I haven''t found a mental connection with how I can assign variables to arrays.. Take for example: def

Hi, I''m really new to rails, so i programmed some stuff and today i read some things about skinny Controllers, fat models. My Controllers are really fat now. So i''m asking myself how can i shrink my controllers and move the code to the models, especially in fact of REST e.g. in focus on error codes? code example: # POST /tasks # POST /tasks.xml def create @authorized

hello, we're considering LLVM as an excellent framework for a compiler backend for a novel dsp architecture based on vliw principles that is still under development. in this context, two students at our institute are particularly interested in the following projects: I) software pipelining apparently [1], there has been already an remarkable amount of work done by tanya lattner
